Tracking and Claiming Tax Deductible Business Expenses in Canada

Every small business has a smattering of expenses to account for and budget for. Rent, utility bills, and office supplies are common and, when totalled together, aren’t insignificant.

For example, in 2019, real estate agents spent 1.3 per cent of their total revenue on rent and another 1.3 per cent on utility bills. These percentages may appear small, but when every dollar counts, it’s important to keep as much of your revenue as possible. As you scale, those small percentages come to represent not-so-small dollar amounts.

Fortunately, many small business expenses may be claimed and written off as tax deductions. The Canada Revenue Agency (CRA) allows businesses to deduct business expenses when they incur to earn income.  

But before you reduce your tax obligation, it’s important to understand what qualifies as a deductible business expense and how to record and claim business expenses in Canada.

How to determine if a business expense is tax deductible

In Canada, business expenses are only tax deductible when the expense is reasonable for your line of work. Reasonable business expenses vary from business to business, as what’s reasonable in one industry differs from that of another.

Generally, business expenses are deemed reasonable if they’re appropriate to your business in both type and cost. For example, you may deduct the cost of your telephone, like your Telus bill, if the expense was incurred for business purposes.

In contrast, the owner of an antique store likely could not write off the purchase of a brand-new motorcycle.

Determining if an expense is reasonable is relatively straightforward. If it’s an expense intended entirely for business purposes, such as the office electricity bill, it would be deemed a business expense. However, what happens if you use a single cell phone for both business and personal use?

In a case like this, you could only claim a fraction of the expense—the portion of expenses incurred for business purposes. If you use your phone for business 20 per cent of the time, 20 per cent of your phone bill would be tax deductible. The same applies to the purchase of the hardware. When possible, it’s advisable you put your utility accounts in the company’s name, rather than your own. Check with your accounting professional before making these kinds of capital expenditures. 

Keeping track of your business expenses

The CRA expects entrepreneurs and small businesses to document and track business expenses. Any business expense that you intend to claim as a tax deduction must be supported by documentation, including:

  • Sales invoices
  • Purchase and sales agreements
  • Receipts
  • Vouchers
  • Cancelled cheques

There are two exceptions to the documentation rule: meal and vehicle expenses. For these expenses, you can use a simplified method. 

Meal expenses are tax deductible based on a flat rate up to a maximum daily allowance. If you opt to deduct the actual cost of the meal (the detailed method), you’re required to treat it like any other business expense, including recording the transaction and keeping relevant documentation.

Similarly, you may use either a simplified or detailed method to claim vehicle expenses as tax deductible. The simplified method uses a flat cents-per-kilometre rate to reduce your tax obligation, though you will need to keep a log of work-related mileage.

It’s a good idea to use accounting or bookkeeping software to record your business transactions and expenses. Many apps include tools to store, sort, and organize your receipts, invoices, and other documentation.

If you’re not the DIY sort, consider hiring a bookkeeper to maintain your books and ensure you’re accurately tracking expenses. Professional bookkeepers specialize in managing business transactions and help ensure your small business is financially healthy—and not drawing the ire of the CRA.

Before you can claim an expense as a deduction, your business must have a reasonable expectation of profit. In other words, you may not be able to claim an expense as a deduction if the CRA has reason to suspect your activities may never be profitable.

For example, income earned from a hobby means you might not be eligible to claim expenses as tax deductions since you never intend it to be profitable. However, you should speak to an accountant to see if it would be wise to have your hobby classified as a business, and therefore eligible to claim tax deductions.

Businesses that aren’t yet turning a profit may have to show the CRA when they expect to be profitable. In this case, you may be able to successfully claim a deduction even if your business hasn’t yet earned a profit.

Why should you claim business expenses in Canada?

Reducing your tax obligations by deducting qualifying business expenses keeps more money in your business bank account—something that’s important at every stage of your business. That extra money could be reinvested into your business to encourage continued growth, used to benefit your community, or to improve the lives of your employees and family.

Whatever your reasoning, tracking and claiming business expenses makes for wiser financial decisions. In doing so, you’re also continually assessing and supporting your business’s financial stability.

Whether you choose the DIY route with bookkeeping software or decide to work with a bookkeeper or accountant, always remember to accurately record business transactions and save, sort, and file any accompanying documentation or proof.

When tax time comes, you’ll be glad you did (and so will your business bank account).
